Abstract (en)
[origin: CA2827090A1] The invention relates to a device (110) for pneumatically conveying powder (42), the device having an injector (111) with a conveying gas connection (93) and a metering gas connection (94) as well as a powder intake channel (100) connected in terms of flow to the injector (111). To achieve the effect that the powder conveying device (110) can be effectively flushed through in the cleaning mode of said device, it is provided according to the invention that a purging gas connection (91), which is connected or can be connected to a purging gas line (103), is provided between the negative pressure region of the injector (111) and the powder intake opening (36) of the powder intake channel (100) for the feeding, as and when required, of purging gas, in particular compressed purging air. Furthermore, a shut-off element (92) is assigned to the purging gas connection (91) to prevent purging gas from being able to escape from the powder output opening (36) of the powder intake channel (100).
